In ver/tor Patented Aug. 25,n 1953 IQ,futur-ED STATE si-.PATENT OFFICE 1Claim. 1

This invention relates to new and useful improvements in cable layingdevices and the primary object of the present invention is to pro- Videa device for plowing in cable, including a cable guide tu-be composed ofhingedly mounted complemental sections that are movable relative to eachother to receive or release a cable or the like.

Another important object of the present invention is to provide anunderground cable layer including a vertical plate having a reartrailing Y edge to which the complemental guide tube sections are hingedand a forward edge that is fixed to a blade having the function ofproducing a cut Y through which the plate and guide tube will be pulled.

A still further aim of the present invention'is to provide anunderground cable layer that is simple and practical in construction,strong and reliable in use, ecient and durable in operation, inexpensiveto manufacture, and otherwise well adapted for the purposes for whichthe same is intended.

Other objects and advantages reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming part hereof, wherein likenumerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the invention in a ditch;

Figure 2 is a plan view of Figure 1;

Figure 3 is an enlarged detail sectional view taken substantially on theplane of section line 3-3 of Figure 1;

Figure 4 is an enlarged detail vertical sectional view takensubstantially on the plane of section line 4-4 of Figure 1;

Figure 5 is an enlarged detail horizontal sectional view takensubstantially on the plane of section line 5-5fof Figure 1;

Figure 6 is an enlarged detail vertical sectional view takensubstantially on the plane of section line 6-6 of Figure 2; and

Figure 7 is a fragmentary perspective view showing the skid spaced fromthe cutter.

Referring now to the drawings in detail, wherein for the purpose ofillustration, there is disclosed a preferred embodiment of the presentinvention, the numeral I6 represents a vertical plate having a straightforward vertical edge I2 and a concave rear edge I 4.

A flat elongated slide plate or skid I6 is fixed by welding or the liketo the lower edgeA of the plate I0 and includes a forward end I8 thatprojects laterally forward from the edge I2. A downwardly and forwardlytapering plow point or Wedge 20 is xed by welding or the like to theupper face of the end I8 and its rear vertical face abuts a pair ofspaced parallel blocks 22 that are fixed by welding or the like to theupper face of the skid I6.

A pair of tube-forming channels 24 are secured to the rear edge I4 by asuitable number of hinges 26 to permit movement of the channels 24toward and away from each other. Pairs of ears 28 are secured to thechannels 24 and these ears 28 are joined by fasteners 30 to retain thechannels 24 in the form of a guide tube. The lower downwardly andrearwardly curved ends of the channels 24 rest upon the rear end of theskid I6 and the upper ends of the channels 24 are outwardly flared toprovide entrance guides 32.

The rear vertical edge of a metallic strip 34 is secured against theforward edge I2 of the plate Ill by a fastener 36 that extends throughthe strip 34 and a pair of spaced straps 38 between which the strip 34is received. The straps 38 are xed by welding or the like to the sidefaces of the plate I0 and project forwardly from the edge I2.

A pair of wings 40 are welded to the lower portion of the strip 34 andtaper toward the beveled forward edge of the plate or strip 34 to form acutter `C whose lower end seats upon the blocks 22 and with the lowerforward corner 42 of the plate I0 positioned between the blocks 22.

The rear ends of a pair of back-to-back channel members 44 are securedagainst the side faces of the plate I0 by bolts 46 and support a boxlikemember 48 to the upper wall of which there is fixed a plate 50, Atransverse sleeve 52 is detachably secured to the plate 50 and the upperwall of member 48 by one or more set screws 54 that will retain ahorizontal pole or rod 56 in the sleeve 52 whereby the device may beguided by two operators holding the ends of the pole 56.

In practical use of the present invention, the forward ends of the beamsor channel members 44 are attached to a tractor whereby the device willbe pulled through a ditch D. The fasteners 30 are loosened to permit thecable `Ca to be extended through the channels 24.

As the device is pulled forwardly, the cutter C will cut through anyobstruction and the plow point 20 will form a channel for the cable.

In view of the foregoing description taken in conjunction with theaccompanying drawings it is believed that a clear understanding of theconstruction, operation and advantages of the device will be quiteapparent to those skilled in this art.

A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention the same issusceptible to certain changes fully comprehended by the spirit of theinvention as herein described and the scope of the appended claim.

Having described the invention, what is claimed as new is:

In combination with a cable laying plow including a vertical platehaving a rear edge with an upper portion which is straight and slopesupwardly and forwardly and a lower portion which curves downwardly andrearwardly, a cable guide comprising a tube divided longitudinally inthev vertical plane of said plateto provide a pair of complementarysections having front and rear abutting edges, each of said sectionshaving a curved lower portion disposed on said curved lower portion ofsaid rear edge and a straight upper portion disposed on said straightupper portion of said rear edge, hinges connecting the straight upperportion of each section to the straight upper portion of said rear edge,the pivotal axes of the hinges of each section being aligned andparallel to said straight upper portion of said rear edge, registeringears on the rear abutting edges of said sections, and removablefasteners securing said ears together, whereby said sections may beswung apart to receive or release a cable or the like.
